One thing Miami did right this season was pick up free agent Dustin Keller. Not only did they prevent their division rival New York Jets from resigning him, but they added a nice offensive weapon to replace Anthony Fasano. Keller is a nice over the middle threat that could find himself in the end zone 8-10 times this season. In addition, Keller should make a nice outlet for Tannehill when he's struggling to move the ball down field. The potential for a very good season is there, we just need to see how often Dustin will be used in the offense.

Update: Dustin Keller sustained a serious career threatening injury. Very sad news as he was expected to be a big part of the Dolphins plans this year. Let's hope that the injury isn't as bad as it looked.

Update (8-16): The Dolphins waived Carpenter in favor of fifth-round rookie Caleb Sturgis, but don't expect the 27-year-old to be out of work for long. ESPN's Adam Schefter reported this week that teams have begun checking in. Carpenter went 51 of 61 on field goal attempts over the past two seasons.

Carpenter may be listed as the Dolphins' number one kicker, but that could easily change come week one. Dan has a pretty hefty salary and his lack of production on the field is not helping his cause. Couple this with Miami's decision to draft Caleb Sturgis and one could infer Carpenter's days in Miami are numbered. No matter if it is Carpenter or Sturgis, the Dolphins' offense needs to move the ball into scoring range for these guys to be useful. Until we see just how well Miami's offense moves the ball this season, it may be best to look elsewhere for a starting kicker.

Update (8-17): It's not often teams draft kickers. Best of luck to the incumbent if they do. In this case, Dolphins kicker Dan Carpenter is now ex-Dolphins kicker Dan Carpenter. Miami waived the veteran in favor of Sturgis, a two-time All-American at Florida. The accurate booter made 24 of 28 field goals with the Gators last season. Nobody should count on the Dolphins right away, but Miami is certainly an AFC sleeper with interesting point-scoring pieces, so watch Sturgis for now.

With so many questions surrounding Miami's offense, this defense could find itself on the field way too much this season. While this could mean sacks and turn overs galore, it more likely means points allowed and few points for fantasy owners. With 20+ defenses ranked ahead of Miami, it is probably best to look at one of them to begin the season.
